ABSTRACT:
An artificial heart valve consists basically of a valve ring and a valve flap in the form of a disc which is pivotally mounted eccentrically in the valve ring, the external circumferential surface of the valve flap cooperating with the internal contour of the valve ring to form a sealing line extending round the circumference of the valve flap. Manufacture of the heart valve can be substantially simplified if the valve ring is obtained by a slightly oblique cut through a hollow cylinder and the valve flap by an oblique cut made at a slightly larger angle through a solid circular cylinder which constitutes the core of the hollow cylinder.
